To all whom t may concern.- ment of the tooth-carrying arm to the frame.Be it known that l, ORLANDO J.

This invention relates to the class of har- Which are arranged obliquelyto the line of 6o i o rows which are equipped with curved springdraftand are securely fastened to each other teeth pivotally connected to theframe, so as to to form the harrow-frame. Said bars maybe allow theteeth to oe set with their points Aor of any desired shape incross-section, and the free ends a greater or less distance beneathparticular means of tying them together is the frame and into a moreorlessinclination to immaterial to my present invention.

The tooth D is fastened out of the ground while drawing theharrowto the exterior or under side of the arm and to and from the iield andalso relieve the in front of the pivot, preferably by means ofteeth-adjusting rods and lever from strain exa clip 7i,-placed astridethe tooth-shank and erted on the teeth when in operation, andthepassingwith its ends through ears formed on -So 3o object, furthermore,is to tie the teeth-adthe arme and provided with nuts by which thejusting bars more securely togetheryand to tooth is securely clamped onthearm. To that end the invention consists in the imguard againstlateral displacement of the proved construction and combination of partstooth the arm c is formed with lugs 7i', which hereinafter described,and specifically set abutagainstopposite edges of the tooth. The 35forth in the claims. attached portion of the tooth is thus entirely Inthe annexed drawings, Figure l is a plan beneath the frame and in frontof the fulview of a harrow embodying my improvecrum of the tooth and thedraft-bar is Within ments, Fig. 2 is a side elevation of the saine. thecurve of the main portion of the tooth.

Fig. tooth is thrown under the frame sufficiently 5 is an enlargeddetached perspective view of to bear on the ground and serve as afulcrumone of the tie-plates` used for' the aforesaid for lifting the frame andthrowing the point purpose and at the same time bracing said of thetooth out of the ground; The tooth hars. Fig. 5 is a plan view of saidtie-plate then serves the purpose of a runner upon roo 5o applied to thehars. Fig. 7 is a side view of which to move the harrow to and from thethe same. 'Figr'S is a plan view of the attach field.

In order to turn all the teeth simultaneously, as aforesaid, theteeth-carrying arms c c are connected together transversely in sets bymeans of transverse rods b l) b, which are coupled to said arms by meansof links b b', which obviate binding or cramping of the connections inthe operation of turning the teeth, as aforesaid. rFhe aforesaid rodsare also coupled together by means of longitudinal bars a a and n. a',which are flat or rectangular in cross-section and placed edgewisevertically and perforated to receive the rods through them. The twoshort bars a a couple the ends of the front and rear rods b b to thecentral rod and the long main bars a d couple the center of the centralrod b to the end portions of the front and rear rods, as more clearlyshown in Fig. 3 of the drawings. Each of these main bars is formed withits central and two end portions l I parallel with each other and atright angles to the rods b b l), and with an oblique intermediateportion 2, which is disposed diagonally' in relation to the aforesaidrods, which pass through eyes in the longitudinal bars, as hereinbeforedescribed.

In order to prevent the longitudinal bars from moving laterally on therods, I secure to the rods the clamps d l at opposite sides of thelongitudinal bars. These clamps I prefer to form of diametricallydividedsections, which are detachably connected with each other at one end by alug i, on one section, interlocking with an eyej in the other section,as shown in Fig. 4t of the drawings. The opposite end of each section isformed with a perforated ear Z for the reception of the bolt, by whichthe clamp is fastened to the rod b. Said construction allows the clampto be applied to or removed from the rod when required withoutdisturbing the longitudinal bars.

The main bars ci a lie with their central portions contiguous to eachother and, in order to firmly tic them together and at the same timebrace them, I apply to the tops and bottoms of said portions of the barsthe tie-plates c e, each of which is formed with the flaring end c andwith the flanges c c, which engage the sides of the bars. The flaringends of the tie-plates are perforated, as shown in Fig. 5 of thedrawings. A bolt passing through the perforations fastens the tie-platesto the bars.

To the barrow-frame, preferably at the rear end thereof, is connected alever L, by means of a toggle or link o, which allows the lever toaccommodate itself more freely to the move` ment of the longitudinal bara, to which the lever is pivotally connected.

By throwing the free end of the lever rearward,as shown by full lines inFig. l0 of the drawings, the longitudinal bars a a a a are drawnrearward, and by their connection with the arms c c, by means of therods b b, the teeth D D are set into the requisite position to cause thepoints of the teeth to enter the ground, and by throwing the lever Lforward, as represented by dotted lines in Fig. l0 of the drawings,theteeth are set into such a position as to carry the longer sweeps orless curved portions of the teeth under the frame and bring saidportions of the teeth to bear ou the ground, so as to lift the fram-eand throw the points of the teeth out of the ground, in which conditionthe harrow is moved to and from the field.

M denotes a notched quadrant, with which engages a dog connected to thelever L and serves to retain said lever in its desired position. Iattach said quadrant to the longitudinal bar a, and thus lock the levermore remote than usual from its fulcrum, thereby affording a more securehold for the lever.

It will be observed that by hinging the arm c close to the under side ofthe frame, extending said arm rearward and upward, and carrying thetooth D forward and over the frame and then downward under the frame, asshown, I greatly relieve the bars b ZJ and lever L from the strainexerted on the tooth when the harrow is in use.

To protect the teeth from wear and abrasion in drawing the harrow to andfrom the field, as aforesaid, I attach to the eXteriors of the teeth theshoes s, by which the teeth ride upon the ground.

What I claim as new is-- l. In a harrow the combination with the mainframe of a spring barrow tooth having a curved runner portion forward ofits point, a shoe secured to said runner portion a tooth holding clipengaging the tooth and pivotally connected to the barrow frame, in rearoi' said shoe, said clip having a part extending upward in rear of saidpivotal connection and adjusting mechanism connected to said upwardlyextending part, whereby when the point of the tooth is elevated the shoewill be lowered into contact with the ground substantially as described.

2. In a harrow the combination with the frame bars, of a spring toothhavinga curved runner portion forward of its point, a tooth clippivotally connected with the frame and engaging the tooth in rear ofsaid runner portion, a shoe engaging said runner portion, a securingdevice for clamping said shoe, tooth and clip, together, said cliphaving an upwardly extending arm in rear of its point of pivoting andadjusting devices connected with said arm, whereby when the point of thetooth is elevated the shoe will be lowered into contact with the ground,substantially as described.

In combination with the teeth-carrying arms c-c and rods-b-bconnecting said arms transversely in sets, the longitudinal bars-aaformed with corresponding central and end-portions at right angles tothe aforesaid rods and with intermediate portions disposed diagonally inrelation to said rod, said longitudinal bars having their centralportions contiguous to each other and perforated for the reception ofthe rods through the1n,and the tie-plates -e-eplaced on the tops andbottoms of the central portions of the longitudinal bars and formed withthe flaring end -e and with flanges -e-eengaging the sides of said barsand perforations -ein the iaring end. -eand the holt passing throughsaid perforations and clamping the plates on the longitudinal bars,substantially as set forth and shown.
